First rooom inside North Gate building. Kill single spawn in entrance hallway, then pather in entrance hallway, then 2 spawn in entrance hallway. Then carefully single pull single mob just inside the room on right side (creep just into doorway and grab him). In the first room there is a 3 spawn on the left side - ph/named is the single spawn just past them on the left. It will agro if you pull all those mobs at once. There are also up to three pathers that wander through and pause inside that room from left and right hallways and staircases. So be careful pulling unless you can split them or tank all of them at once. Named is fairly common - about once every 90 minutes or better and neither aug seems more common or rare than the other. I've farmed a dozen or more for guildmates/friends.
Over the last few years i have farmed this aug for guild mates and several of my alts and the Warpower Stone is a lot more uncommon then the orb aug. at least a 5-1 ratio imo.
update on this guy's loc N1366 P3328, opposite of earlier post, looking at the map,very top of map ,in the big building right next to big thron(chair) between double staircase as you enter. No named updated anywhere near this camp on mapfiends, but the mobs include quite a few "royals."
Ok not sure if I am missing something here, but me and hubby went out to Vald last night to see where that mob spawns. Went to the very top north room with the double staircases, went up those and then down again. As soon as we clicked on the door we had the whole room on us, sk fd'd and I gated. In that room was a named called Royal Cryptguard Zerakt. After I ran back out there we went to that above mentioned loc -1366, 3328 which brought us way down south close to the pit. Where we at the correct room north?
